PROCESS OF EXTEACTING WAX FROM THE CANDELILLA-PLANT.

No Drawing.

Specification of Letters Patent.

Application flied October 30, 1911.

To all whom it may concern 7 Be it known that I, BENJAMIN YOUNG SHARP, a citizen of the United States, residing at Uvnlcle, in the county of Uvolde and Shite of Texas, have invented new and useful Improvements in Processes of Extracting Wax from the Candelills-Pisnt, of which the following is s specification.

This invention relates to the process of extracting wan l'rom the csndelills. blunt by means oi? gssolene, benzin oi'-iisphthn,'ancl has for its object to secure c. WZLK of light yellow color, instead of the dark green wax ohtnined by the processes now in use.

In extracting ccndclillo Weir by means of El. volatile mineral oil, a. continuous flow of the oil passes from the fdigcslor cont-oining' the plant, to the evaporator, Where sulllcient new is applied to evaporate the oil, which goes over into a condenser, and flows from' there hnclr into the digester. This lcnves the Wax Wl'lichis drawn from the h0tllOll'l of the evaporator.

The resulting we): of this process, is of dark green color. I boil the plant containing the Wax, in the volatile mineral oil, in the presence of lullers earth, for a, sulliclent length of time to entrust the Willi frmn the plant. I then adopt either of the following methods of procedure:

1st. I pass the entire fluid into a separate tank where it is allowed to stand till it settles and becomes clear. The clear liquid is then drawn oil and passed into the evaporator Where the oil is driven oil by heat and recovered in the condenser i :l the we); is drawn from the bottom of the "operator.

2nd. Or the fluid is passed through a filter, from the digestcr directly to the eve )orator where the process is continued as in t c first instance.

The wax obtained by my process is of light yellow color, and has a greater commercial value than the dark green wax 0btsincd by other processes of gnsolcnc, bcnzin or naphtha extraction.

I claim:

The process of extracting canclelills won: from'the candelilln plant, consisting in boiling the plant in gnsolene, benzin 0r naphtha. in the presence of fullcrs"earth and clerifying the liquid before evaporating the volstile oil to recover the wax, substantially as herein described.

BENJAMIN YOUNG SHARP.
